Recap: Upgrade Shop

Part of the Building Real Games section of Coddy's Unity journey. Lesson 11 of 56.

Challenge

Easy

A gold mine you dig by clicking. Write GoldMine.cs (the scene links the three buttons and the three texts):

Each click on Mine earns coins, 1 per click at first. coinsText shows them, as Coins: 12.
The pick costs pickCost (10). Buying it spends the coins, adds 1 to the coins per click and raises its price by 10. Its button's text, pickText, shows the price, as Pick: 20.
The lantern costs lanternCost (25) and can be bought once: it adds 3 to the coins per click, and from then on lanternText reads Lantern: owned. Before that it reads Lantern: 25.
An upgrade's button is interactable only while you have enough coins for it, and the lantern's never again once it is owned.
All three texts and both buttons are right from the start.

Press Play, dig, buy both upgrades, then Check.

public class GoldMine : MonoBehaviour
{
    public Button mineButton;
    public Button pickButton;
    public Button lanternButton;
    public TMP_Text coinsText;
    public TMP_Text pickText;
    public TMP_Text lanternText;
    public int pickCost = 10;
    public int lanternCost = 25;

    // Mine earns coins; the pick and the lantern are upgrades, usable only when you can afford them
